HEADLIGH DIMMER.

, Application filed January 13, 1926. Serial No. 80,920.

. ment, to eliminate the glare of the headlights of an automobile, andalso means to enable the ready application of the device to the standardtype of head-light.

Another object of the invention resides in the provision of readilyattachable clamp ing bands adapted to carry the dimmer hood and thebearings for the hood actuating shaft.

A third object of the invention resides in the provision of readilyattachable clamping bands adapted to carry the dimmer hood, the bearingsfor the hood actuating shaft, and means to conceal the band clampingmeans to render the device more artistic in appearance.

Other objects of the invention are mentioned and described herein.

The preferred embodiment of my invention is illustrated in theaccompanying drawing in which Figure 1 is a side elevation of an autohead-light showing my improved dimmer mounted thereon; Fig. 2 is a frontelevation of an automobile illustrating the application of my inventionto the headlights thereof; Fig. 3 is a top plan view of one of thedimmer hoods and the actuating elements connected therewith; Fig. 4 is afragment of one of the hood carrier bands showing one shaft bearingelement applied thereto; Fig. 5 is a view of the same element at rightangles thereto; and Fig. 6 is a section taken on line 6-6 of Fig. 4E.

Similar numerals of reference indicate like parts throughout the severalviews on the drawing.

Referring to the details of the drawing, the numeral 1 indicates anautomobile fragment provided with the two spaced headlights 2, 2suitably mounted upon brackets 3, 3 secured in the frame of the car inthe usual manner, which said brackets may be connected by a transverserod 4 to steady the lamp unit.

The invention herein contemplates a glare eliminating hood or dimmer 5carried by each of the lamps 2 and movab-ly mounted upon a splitclamping band 6 which is readily attachable to and removable from eachlamp, as hereinafter described, together with means operative from theauto dash for simultaneously actuating said dimmer hoods.

In Fig. 1 of the drawing the normal position of the hood 5 is indicatedby the full lines thereof, and the dottedlines thereof indicate thedepressed or glare eliminating position thereof. 1 Both hoods 5, and thetwo bands 6, respectively, are of similar construction and a descriptionof one of each will suffice.

Each band 6 is preferably made of sheet or strap metal and divided, andformed circularly to encompass the cylindrical body of the lamp 2, thedivision point of the band being provided with integral end lugs '7 and8 in'which the clamping screw 9 is mounted. The outer end of band lug 8is extended at 10 and downwardly, at right angles, to cooperate with lug7 to partially conceal the screw 9. The arch-like hood 5 is tiltablyarranged above the band 6 and is provided with a pair of spaced hingelugs 11 which are hingedly connected with corresponding hinge lugs-12rigidly connected with the band 6 and projecting forwardly therefromabove the divided portion of the band. And each hood 5 is provided witha single arm 18 extending laterally from one side thereof and adapted topivotally carry the forward end of the actuating link 14, the other endof said link being pivotally connected with the outer end the lever arm15' at 16, said lever arm being rigidly secured to the horizontallyarranged rock-shaft 17 which extends transversely of the car front andbetween the lamps 2 and is ournaled at its opposite ends in the bearingeye 18 of the element 19. The bearing element 19 is secured to the upperface of the band lug 8 by the head of the screw 9 and is provided withthe extension 20 which is right angularly bent downward to cooperatewith the band lug 7 and the lug extension 10, to effect completeconcealment of the screw 9, Fig. 6.

The numeral 21 indicates a coil tension spring the lower end whereof isanchored in the rod l, the upper end thereof being connected with thearm 15, adjacent the outer end thereof, to normally hold the hood 5elevated. The numeral 22 indicates an arm depending from the rock-shaft17 and rigid Obviously, the full line position of the hood, e.- tte sd;itefsdtwi ing, efteets'the' full and un immedli-ghtr 'ayfroin the lamp.To dim the light theoar driver tilts the hand lever 2% ,tothecdottedline position thereof, as illiistfated in 1, thereby depressing thefront end oft-lie hood 5 to the dotted line position thereof.

I claim:
